Geological units modelled
In total, 64 superficial and artificial geological units were modelled (including mass movement deposits). Table 1 lists the units in broad stratigraphic order together with the BGS stratigraphic lexicon code for each (see https://www.bgs.ac.uk/lexicon/) and lithology. Standard BGS map colours have been used for all superficial units in the model (Figure 2). These should be referred to when viewing images of the model in this report. Note that the Head and Clay-with-flints deposits are known to be polycyclic, and in the case of the latter, its formation is likely to have started as early as the Pliocene
Inferred' 'age | LEXICON' 'CODE | Full name | Lithology |
Holocene deposits and artificially modified ground | slip | Landslide deposits | Mass movement deposits; variable composition, dependent on the nature of the upslope material |
wgr | Worked Ground | Artificially lowered area, or void, through man-made excavation, e.g. a gravel pit | |
mgr | Made Ground | Artificially raised areas, variable composition | |
wmgr | Worked & Made Ground | Area of artificial cut and fill, e.g. a backfilled quarry, variable composition | |
ddgr | Disturbed Ground | Area of disturbance associated with surface or near-surface collapse | |
lsgr | Landscaped Ground | Extensively remodelled areas where it is difficult to delineate zones of Made, Worked or Disturbed Ground. Variable composition | |
peat | Peat | Humic deposits, consisting of wet dark brown partially decomposed vegetation |
